Taiwan air quality today The AQI right now, city by city

Right now the 18 cities Airleaf measures in Taiwan average AQI 54 (moderate). The worst air is in Tainan, at AQI 71, and the cleanest in Taipei, at AQI 42. At ground stations alone, which measure rather than estimate, the average is AQI 54 across 18 cities. None of the 18 measured cities is over AQI 100 today, and 44% have Good air.

Tainan, at AQI 71 (Moderate) on the US EPA index. Unusually sensitive people should consider limiting long outdoor exertion.

Taipei, at AQI 42 (Good). Both lists rank current readings, from ground stations wherever Taiwan has at least three cities with one.

It depends on the city. 8 cities are Good, 10 cities are Moderate. At the national average of AQI 54: Unusually sensitive people should consider limiting long outdoor exertion.

About 50,800 ha from 2001 to 2025, 2% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 19,800 ha of it was cleared for good, for farms, mines or towns.

Xizhi, with 61.0% tree cover within 2 km of its center, measured from Sentinel-2 satellite images.

Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
